a cheap refreshing drink that comes in the form of a powder in a packet. Comes in many, many flavors. Just add water. Non-carbonated, the drink is promoted on TV by the walking Kool Aid pitcher. He holds a picture and a cup filled with the drink and says "Ohhhh yeahhh!" as he crashes through a wall. Jim Jones and his People's Temple cult in the Jonestown compound in Guyana commited mass suicide by drinking Kool Aid laced with cyanide.

"Kool-Aid" is what one drinks metaphorically, in the context of a political campaign, when faced with an eminent loss. The term was popularly referenced in the 1993 film, "The War Room" by George Stephonopolous when he states, "I'm afraid we're all going to have to drink Kool-Aid."

The term references the Jonestown massacre in 1978 when all of its inhabitants were directed to ingest cyanide-laced Kool-Aid.
